Journal Title: 广东农业科学 - Year 2018, Vol 45, Issue 6
Abstract
"In recent years，in Huiyang District，the main line of work is“production stabilization，income increase，structure adjustment，and institutional transformation.”They deeply carried out the action of zero growth of chemical fertilizer，constantly explored the new model of saving and improving efficiency technology of chemical fertilizers，vigorously promoted soil testing and formula fertilization technology，soil organic matter upgrading technology，irrigation and fertilization technology，organic fertilizer instead of fertilizer technology，through project support，government subsidy and expert guidance，etc. Since 2014，some achievements were achieved in the popularization of saving and improving efficiency technology of chemical fertilizers. The concept of farmers' fertilization was obviously changed. The quality of cultivated land was significantly improved，soil organic matter rose by 0.1～0.9 g/kg，soil nutrients were obviously improved，soil structure was improved，and soil consolidation and acidification were improved. The fixed point survey showed that，the average amount of fertilizer used for planting rice and yam was reduced by 23.1 and 32.4 kg per 667 m2，respectively，and the reduction was 33.82% and 16.10%，respectively. Farmers' enthusiasm for the use of organic fertilizer gradually increased. The plan of zero growth of chemical fertilizer，proposed by the Ministry of Agriculture，was initially realized. In general，the fertilizer application amount（ pure quantity） reduced by 468 t（ reduction percent was 4%）. In Huiyang District，the supply of agricultural products is effectively guaranteed，the green agriculture is accelerated and the Rural Revitalization is steadily advancing."
